Do your research, ask yourself what your doing this for. Fun, money, to show fish. Make sure you have a reason, and are not just breeding cause it's cool or you can. Make sure you have a direction your going.
Make sure you have everything. If you don't have the right breeding supplies, the fish is suffering.
Food for the fry, so many people breed. Once they have fry then they think about food. So think a head and just check over everything, go over every step in your head & research..
